312 STALK-EYED CRUSTACEA 



longation which termhiates in the front is short, but 

 very distinct and a little elevated. The front, deeply- 

 notched in the centre, is advanced in the form of two 

 small obtuse horns in front of the epistome. The superior 

 orbital borders have on the outside two fissures more or 

 less distinct. The antennulary fossae are very oblique, 

 but small, and their external angle is advanced much 

 in front of the orbits. The buccal cavity, triangular, 

 is separated from the pterygostomian regions by a 

 prominent and straight border. The first pair of legs 

 thin and very long, about twice the length of the body ; 

 the hand contracts much towards the origin of the pincers, 

 and is twisted on its axis so that the fingers open in a 

 vertical plane. The fingers are armed with small conical 

 and very pointed teeth, separated by similar but longer 

 teeth. The other legs are almost cylindrical and very 

 long ; those of the second pair are about once and a half 

 times the length of the carapace ; their last joint is 

 styliform, and laterally compressed rather than depressed. 

 The abdomen of the male has the first and last two 

 segments free, and the three intermediate segments 

 soldered together. In the female the penultimate seg- 

 ment is soldered to the preceding segments.

 and directed backwards. The pterygostomian region is
